I want to use 2 xantech kits to send and receive the ir to and from my sony 777es receiver.
Anyone done this?
Is there frequency issues that make this impossible?
The ir from the lcd remote works fine through a remote extender kit that I built to do something else so I cant see a problem....anyone want to spoil my fun???

I hope not. I'm planning on doing the same thing with my Sony 9000es preamp. I imagine it could take some careful placement of the IR receiver and transmitter within the room (for the remote) to avoid a feedback loop though.
